FIELD OF THE INVENTION

The present disclosure relates to fin systems and fin carriages in waterboards.

BACKGROUND OF THE INVENTION

The following description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.

All waterboards, such as surfboards and/or stand-up paddleboards, utilize fins to provide both maneuverability and stability. Various fin arrangements exist within the surf industry, such as, for example, single fins, dual fins, three fins, four fins, and five fin designs. Regardless of fin arrangement and or number of fins used as preferred by the individual surfer, placement of the fin(s) is crucial to performance of the waterboard. Exact fin placement is typically defined and marked onto the individual board by the originating shaper or designer of the board.

The use of fin retention devices is prominent within the present water sport industry, such as the surf industry. These components are popular as they allow fins to be easily removed and reinserted. The vast majority of all fin-to-fin retention devices are accomplished with the use of a grub screw which when tightened locks the fin into a fin retention device. An industry standard 3/32 hex surf key is used to accomplish this task. Fin retention devices are available in various styles, be it for ease of installation, or strength. The majority of all devices used within the surf industry are designed around two primary fin insertion forms, a single continuous tab or a split dual tab. However, in all cases, once a fin retention device is adhesively inserted (glassed) into a surfboard or stand-up paddleboard, it is permanent. Thus, in most cases the orientation of the fins(s) placed into them is then permanent as well. Final placement (adhesion) of the fin retention device is accomplished at a glassing facility.

Thus, there remains a need in the art for new fin retention devices that allows a user to easily remove and reinsert a fin, and/or alter the orientation angles of a fin.

Referring now to the drawings, wherein the drawings are for purposes of illustrating embodiments of the present disclosure only, and not for purposes of limiting the same, FIG. 1 provides a view of the fin retention system 100 with accordance with embodiments of the disclosure. In one embodiment, the fin retention system 100 is a 3-axis adjustable fin retention system 100 that allows user-controlled movement of the fins 102 after installation o. In one embodiment, the movement may be fore and aft movement of up to half inch. In another embodiment, the movement may be side to side (vertical) angular movement. The angular movement is preferably in increments of +/−1 degree, +/−2 degrees, +/−3 degrees, +/−4 degrees, +/−5 degrees, +/−6 degrees, +/−7 degrees, +/−8 degrees, +/−9 degrees, and/or +/−10 degrees per side. In another embodiment, the movement may be planar (horizontal) angle rotation movement of up to and in increments of 1 degree, 2 degrees, 3 degrees, 4 degrees, 5 degrees, 6 degrees, 7 degrees, 8 degrees, 9 degrees, and/or 10 degrees. In one embodiment, all adjustments and locking are done by using a standard surf key. In one embodiment, a non-biased base can be used on either side of the board. The various lengths and angles disclosed herein provide some examples in which the fin retention system is adapted for movement. As would be clear to a skilled artisan in the art, the present disclosure is not limited to the specific lengths and angles disclosed herein—variation in the lengths, angles, and other components are permissible without departing from the spirit of the disclosure.

Referring now to FIG. 2 , in one embodiment, the fin retention system 100 disclosed herein comprises the following components—an outer carrier or board housing 202, an inner carrier or fin housing 204, a fin carrier or fin carriage 206, and optionally an end cap 208. Throughout this disclosure, the terms “outer carrier” and “board housing” are used interchangeably. Throughout this disclosure, the terms “inner carrier” and “fin housing” are used interchangeably. Throughout this disclosure, the terms “fin carrier” and “fin carriage” are used interchangeably. In some instances, the fin housing 204 is optional, in which case the fin carrier may directly slide into the board housing (FIG. 9 ).

Referring now to FIG. 3 , in one embodiment, the fin retention system 100 disclosed herein comprises the following fastening components—a forward cap screw 302, an aft cap screw 304, two inner carrier grub screws 306, two inner carriers to end cap shear pins 308, and a fin grub screw 310.

Referring now to FIG. 4 , the outer carrier 202 may further comprise two permanently attached threaded fastener inserts 210 pressed into the outer carrier 202. The outer carrier 202 may be adhesively installed (glassed) into a surfboard or stand-up paddleboard. The outer carrier 202 is specifically designed to be installed in a manner consistent with existing surf industry fin retention device installation methods; typically, a routing template and a specifically sized router bit are utilized. No additional special tools and or equipment are necessary. The outer carrier 202, once installed, allows the remaining fin retention components, such as for example, the inner carrier 204, the fin carrier 206, and the end cap 208, to be assembled and releaseably attach into the outer carrier 202.

The board housing or outer carrier 202 may be glassed into a surfboard in various quantities and configurations depending on the number of fins desired. Usually one, two, three, four, or five board housings may be installed in the surfboard. The number of fins and its configuration may be varied depending on the user experience and the type of surf/wave. Tri-fins (3 fins) and Quads (4 fins) are most commonly used in surfing. A five-fin configuration may also be used, although users may choose to not use all five fins at the same time. Installing five board housings would allow a user to mix and match fins, for example to tri-fins or quads, depending on their preference and the surf conditions. It is contemplated that a user would glass their preferred number of board housing or outer carrier 202 into the surfboard.

FIGS. 5, 8, and 9 , further elaborate various embodiments of the inner carrier (fin housing) and the fin carrier (fin carriage). As shown in FIG. 5 , in one embodiment, the inner carrier 204 further comprises two grub screws 306. In one embodiment, the inner carrier 204 serves four functions. The first function is to house the fin carrier 206. The second function is that, once placed into the outer carrier 202, the inner carrier 204 provides the horizontal adjustment sweep capabilities. The forward cap screw 302 location common to the outer carrier 202 and the inner carrier 204, that is the threaded insert 212 of the outer carrier 202 and the cap screw 302 of the inner carrier 204, provides the pivot axis and location for this function. The third function is to utilize the two grub screws 306 to adjust and lock the fin in the fin carrier 206 into the desired orientation. The fourth function is to align and then capture the end cap 208, via two internal shear pins 308, which, once inserted into the inner carrier 204 and end cap 208, allows for final retention, tightening and alignment in the horizontal orientation. In one embodiment, retention is accomplished using standard cap headed screws—one through the inner carrier 204 into the outer carrier 202 forward insert and one through the end cap 208 fitting into outer carrier 202 aft insert.

FIGS. 8 and 9 show another illustration of the various components of the fin retention system 100. The inventor contemplates at least two different embodiments of fin carriers 206 that can be housed in the fin housing 204. The fin, either a Future fin or a FCS fin, may be installed into the fin carrier 206 by simply pushing it down. Upon such installation, the fin carrier, optionally together with the fin, is slided into the fin housing 204. The fin housing is then pushed down into the board housing. One or more of the fastening components (a forward cap screw 302, an aft cap screw 304, inner carrier grub screws 306, two inner carriers to end cap shear pins 308, and a fin grub screw 310) are then tightened before use in surfing.

Furthermore, the fin retention system disclosed herein enables the fin to be installed at an angle or cant. Fin Cant is the degree of outward angle a fin has in relation to the bottom of your surfboard. If a fin has zero cant, then it is positioned at a right angle to the board. To enhance rider-to-board connectivity and responsiveness, especially through turns, surfers usually prefer canted fins. On the other hand, the less cant a fin has the more drive and acceleration the board will have. The fin housing 204 disclosed herein have inner grooves or rails (FIG. 12 ), such that the fin carriage 206, having a ridge on the outside, may be slided in at different predetermined angles or cants. The cant settings may be adjusted by the user. Preferably the grooves in the fin housing 204 have cant settings of 0 degree and/or in increments of 1 degree, 2 degrees, 3 degrees, 4 degrees, 5 degrees, 6 degrees, 7 degrees, 8 degrees, 9 degrees, or 10 degrees. The ridge of the fin carriage fits into the groove (or rail) of the fin housing firmly, creating a tight, solid seam, reducing (or in some cases, eliminating) the need for additional screws. Alternatively, in some embodiments, it is contemplated that outside of the fin carriage 206 will have grooves/rails that fits into ridges present in the inside of the fin housing 204. The rails/grooves/ridges allow the fin carriage 206 to slide in symmetrically along the centerline of the board in predetermined set angles. As discussed earlier the predetermined set angles are in in increments of 1 degree, 2 degrees, 3 degrees, 4 degrees, 5 degrees, 6 degrees, 7 degrees, 8 degrees, 9 degrees, or 10 degrees.

Referring now to FIG. 6 , in one embodiment, the fin carrier 206 further comprises a fin locking mechanism. Depending on the type of fin locking mechanism, the fin carrier 206 may further comprise one, two, or more grub screw(s) 310. In one embodiment, the exact number of grub screws 310 used is based on the specific manufactured fin style to be desired by the user. The fin carrier 206 is intended be made in multiple configurations to accommodate multiple fin locking styles. In one embodiment, the fin carrier 206 serves three functions. The first function is to provide locking capability for the desired fin style, utilizing the attached grub screw(s) 310. The second and third functions are to provide two orientation adjustments and their respective retentions. One adjustment is for the forward and aft placement of the fin carrier 206 while contained within the inner carrier 204. Movements in ⅛-inch increments are possible and are provided for by the angled cusp features 212 located on both sides of the fin carrier 206. The second adjustment is for vertical angularity of the fin 102. In one embodiment, the cusp features 212 on the sides of the fin carrier 206 allow interface between the grubs screws 306 contained in the inner carrier 204. Angular adjustments are accomplished by adjusting the depths of the two grub screws 306 contained in the inner carrier 204. User visual reference for forward and aft movement of the fin carrier 206 is provided by small holes spaced at ⅛-inch increments in the top of the carrier. Visual references for desired fin 102 angularity are also provided by small holes placed into the sides of the fin carrier 206. Reference spacing of one-degree increments are provided.

Referring now to FIG. 7 , the end cap 208 provides two functions. First is to mate via two small shear pins 308 to the inner carrier 204. Once mated, the inner carrier 204 and the end cap 208 act as a single entity to provide vertical rigidity and retention for the fin retention system 100. The second function is achieved through the use of the slotted feature within the end cap 208. This feature allows for horizontal sweep adjustability of the end cap 208. Final capture is achieved by tightening of the aft cap screw 304 within the end cap 208, which threads into the threaded insert 210 located within the outer carrier 202.

In one embodiment, and as discussed throughout the disclosure, the fin retention system 100 disclosed herein, provides the ability for surfers to easily adjust fins on waterboards (such as surfboards and stand-up paddleboards) in at least three critical orientations. In one embodiment, in the forward and aft orientation, a total adjustment of a ½ inch is possible. Movement is allowed in ⅛-inch increments. Adjustment is visually notable to the user by indicators built into the fin carrier 206 (FIG. 6 ). In the vertical angle orientation, 3 degrees of angle per each side (total of 6 degrees) per side is possible. Visual guides built into the fin carrier 206 are available in 1 degree increments for user reference (FIG. 6 ). In the planar angle orientation, a total sweep of 3 degrees is possible. Degree orientations between zero and three, per side are possible. Visual guides built into the end fitting (FIG. 7 ) are available in 1 degree increments for user reference.

In one embodiment, the instant fin retention system 100 disclosed herein provides the surfer with the ability for two important user-friendly features: retention hardware commonality and fin insertion style flexibility. All fin orientation adjustments are performed by the loosening/tightening of a minimal number of fasteners. All fasteners used in this invention utilize the 3/32 hex surf key (Allen Key) typically carried by all surfers. It is the only tool required to make adjustments.

In one embodiment, one feature of the fin retention system 100 disclosed herein is the ability to easily remove and replace the internal fin carrier 206 or fin housing 206 (FIG. 6 ). Depending on manufacture and surfer fin preferences, the internal fin carrier or fin housing 206 would accommodate multiple fin insertion styles. This provides the surfer with almost unlimited fin selection.
